Recently got this error on my Xbox 360 4GB slim shortly after the 1 year warranty expired on the console. (Just over 2 weeks of expiring)
Turned it on for the first time in a couple of days and got hit with the 4 red lights, after doing some reading on it it's usually an HDD error (which I don't have) or a NAND corruption or bridge failure which is more likely.
Seeing as this occurred shortly after the 1 year warranty period Micro$oft probably won't repair it evidently as their online repair center is seeking $80+ for repair costs DESPITE cutting the 12 month warranty down to 11 months without notification or just cause. Online website says console warranty expired on February 15th 2013 however my store receipt and credit card statement both list date of purchase as March 15th 2013.
Anywho, thank you for your OUT OF THIS WORLD level of customer service and ARBITRARY cutting of a standard warranty without cause or notice.
Bought March 15, 2012 from local Future Shop
12 month warranty that ends on March 15, 2013...?
April 1st 2013, Xbox 360 gets E79 error --> Check repair site/warranty
Warranty expired on February 15th 2013...Look at receipt and credit card statement....Both says it was purchased on March 15th 2012.
Thanks for arbitrarily cutting a month off warranty without notice or just cause & being steller in offering a reduced warranty (from 3 years) on a lower quality product
